Can J2EE applications work with ABAP ?

[Former Member]

Hi all,

I am a newby in the SAP world.

I want to development J2EE applications and run them in the Netweaver J2EE engine. My J2EE applications also have to co-operate with ABAP programs (or function call's from SAP's HRM, CRM and other business suites) and vice versa.

Can anyone let me know if that's possible and send me URL links to documention to read more about it?

Thanks in advance,

Hi Thiel,

well, there are many resources available for that:

The <a href="http://help.sap.com/saphelp_nw04/helpdata/en/6f/1bd5caa85b11d6b28500508b5d5211/frameset.htm">SAP Java Resource Adapter</a> is a JCA 1.0 compliant J2EE connector to access ABAP backends in the transactional environment of the J2EE engine.

The <a href="http://help.sap.com/saphelp_nw04/helpdata/en/6f/1bd5c6a85b11d6b28500508b5d5211/frameset.htm">SAP Java Connector (JCo)</a> is internally used by SAPJRA and provides an API to access RFCs/BAPIs from Java and vice versa.

The <a href="http://help.sap.com/saphelp_nw04/helpdata/en/ed/897483ea5011d6b2e800508b6b8a93/frameset.htm">SAP Enterprise Connector</a> is a tool to generate easy to use proxies, which prevents the developer to use the sometimes complex JCO API.

And last but not least, the <a href="http://help.sap.com/saphelp_nw04/helpdata/en/01/90fd3f0521c842e10000000a1550b0/frameset.htm">RFC engine service</a> can be used to call session beans residing in the J2EE engine by an ABAP system.

Happy reading
